README
Mock 
Mock is a doubles (stubs and mocks) library for Crystal, inspired by the API of rspec-mocks (but it implements a small basic subset of it to the date).
Installation
Add this to your application's shard.yml:
development_dependencies:
mock:
github: porras/mock
You can now run shards to install it.
Usage
Require it in your tests and you can start using it.
require "mock"
Creating a double
Just call the double() method.
Stubbing a method
Calling stub on that double object will set a method stub:
my_object = double()
my_object.stub(:my_method)
You can establish a return value for the stub method (if you don't, method stubs return nil):
my_object = double()
my_object.stub(:my_method).and_return("my value")
my_object.my_method.should eq("my value")
You can also filter my arguments, establishing different stubs for the same method:
my_object = double()
my_object.stub(:my_method).with(1).and_return("value 1")
my_object.stub(:my_method).with(2).and_return("value 2")
my_object.my_method(1).should eq("value 1")
my_object.my_method(2).should eq("value 2")
Setting expectations
You can also set the expectation that a method will be called, and it will be automatically checked at the end of the test:
my_object = double()
my_object.should_receive(:my_method).with(1).and_return("my value")
# if we omit this line, the test will fail
my_object.my_method(1).should eq("value 1")
See example_spec.cr for more examples.
